juile is making a nacklace out of red, green, and white beads. she strings the beads in order shown above and and continues the pattern. each bead is 1/4 inch in diameter. how many beads of each color will she need to make a necklace 24 inches long?

Since each bead is 1/4 inch in diameter, the necklace will have 4 beads per inch. Multiplying 4 by 24 gives you 96 beads all together.
Divide 96 by 3 to find the number of each color of beads she'll use. 
32 beads of each color
each group of beads is 3/4 inch long and 24 divided by 3/4 = 32 groups or 32 of each bead
